'An important object of the inventionis'to provide a cook stove of the above mentioned character, which is simple in construction, cheap to manufacture, and easy to operate.

A further object of the invention is to improve the construction of this class of stoves ingeneral and to provide a device which is compact and neat in appearance.

Other'objects and advantages of the invent-ion will be apparent during the course of the following. description.

In the accompanying drawings forming a part of this'speoification and in which like numerals are employed to designate like parts throughout the. same, Figure 1 is a front elevation ofthe stove, Fig. 2 is a plan view of the same, Fig. 3 is a transverse verticalsectional view'through the same taken on line 33 of Fig. 2, Fig. 4 is a detail view of a damper or valve for'controlling the en trance of. air into the oven, Fig. 5 is a sectional view through the same, Fig. 6 is a vertical longitudinal sectional view through the stove taken on line 6-6 of Fig. 2, Fig. 7 is a vertical sectional view through the damper or valve for controlling the entrance of heated gases or products of combustion into the oven, and Fig. 8 is a side'elevation of the same.

Inthe drawings wherein for the purposes of illustration, we have shown a preferred embodiment of our invention, the numerall designates an outer preferably, rectangular casing formed of sheet-metal and mounted upon legs 2. Connected with the upper end ings 6, which are closed by removable lids of this casing is a top or cover 3, carrying near its corners, upstanding posts 4, to which are connected horizontal rails 5. The topl3 is provided with a suitable number of open- 7, having openings or outlets8 formed therethrough, as shown. These openings 6'have the upper endsof sleeves or titles 9 leading thereto, as more clearly shown in'Fig. 6.

Disposed within the casing 1 are downwardly converging plates or walls .10, which V areconnected at their upper ends with the. casing 1, as shownat 11. At their lower ends, these plates 10 are bentto form horizontal hollow fixed supports 12. Theplates l0 and their supports12 extendlongitridinally for the entire length of; the casing 1. The plates 10 form with the rear? and front walls of the casing 1, an inner heating 7 l chamber 18. The plates "110 are provided upon their inner faces with sheets of asbestos 1 1 or the like. The top or cover 3 has its lower face covered by a sheet of asbestos 15 and the rear end wall 16 of the casing 1 has its inner face covered by a sheet of asbestos 17 Disposed within the plates orside walls 10 ofthe -heating chamber 13' are spaced intermediate'shells 18 and 19, formed of as,- bestos or other high heat resisting material. 7

These shells-18 and 19 have itheir'side walls converging downwardly while their rear end walls are vertical and remain in spaced parallel relation tofthe rear'wall 16- of the casing 1, as shown. The forward ends of the shells18 and 19 are formed open and en-' gaged with the forward end wall of the casing 1, as clearly .shown in Fig. 6. The shells 18' and 19 are held in' their proper spaced positions by spacing elements 20, or other suitable means. The upper walls of the shells 18 and19are provided with openings through which the fines or sleeves 9 pass. The lower ends of the side walls of the shells 18 and 19 extenddownwardlytoengage the fixed supports 12. Attention is called to the fact thatthe shells 18 and 19 form heating spaces 21 and 22, which are closed at the tops. i

Disposed within the shell 18 are horizontal upper and lower spacedPovens 23 and 24 which extend longitudinally within thecasing 1 and at their forward ends lead into openings 25 and 26 respectively, which are formed in the forward end wall of the casing 1. The opening 25which leads into theov en 23 is normally closed by swinging doors 27 which are hingedto the casing 1, as shown at 28. These doors may be held in their closed positions by any suitable means. The opening 26 whichleads into the oven 24is I normally closed by a vertically swinging door29, hinged to the casing 1, as shown at 30. Any suitable means may be employed to hold this door closed. The oven 23 is preferably divided into upper and lower compartments by a horizontal removable tray 31, supported by fixed brackets 32. The ovens 23 and 24 are also held in their proper positions by the spacing elements 20.

Disposed between the ovens 23 and 24 is a heating coil or pipe 33 having connection with a tank or other source of water supply (not shown) and discharging in any desired manner.

Air supply pipes 34 pass through the plates 10 and shells 18 and 19 and have their inner ends discharging into the upper portions of the ovens 23 and 24. Each of these air supply pipes has its outer end flared, as shown at 35 and engaging the side walls of the casing 1. The side walls of the casing 1 are provided with openings 36 which lead into the flared portions 35 and the passage of air through the openings 36 is controlled by rotatable dampers or valves 37, having openings 38 adapted to be moved into and out of registration with the openings 36. The valve 37 is disposed upon the outer face of the casing 1 and operates within fixed brackets 39 attached thereto. The valve or damper 37 is turned by a central stem 40 provided with a knob 41. The ovens 23 and 24 are provided upon their opposite sides and near their lower ends with gas inlet openings 42, adapted to be covered and uncovered by a valve or damper 43, provided with openings 44 for movement into and out of registration with the openings 42. Each of these valves or dampers is disposed upon the inner face of the oven and operates within fixed brackets 45 rigidly connected with the oven. Each of the valves or dampers 43 is turned by a rod 46, provided at its inner end with a crank 47, carrying a finger 48, which extends within an opening formed in the valve 43 and operates within a curved slot 49. The rod 46 operates in an opening formed through a fixed plate 49. The rod 46 extends through and beyond the casing 1 and is provided at its outer end with a knob 50.

Disposed within the heating chamber below the oven 24 is a horizontal removable gas burner 51, which is removably mounted, through the medium of legs 52, upon removable hollow supports 53. The supports 53 are provided at their upper portions with pins 54, rigidly connected therewith and adapted to fit within openings formed in the upper portions of the fixed supports 12. The lower portions of the removable supports 53 are connected with the bottom wall of the casing 1 by screws 54 or the like. The bottom wall of the casing 1 is provided with a main opening 55, through which the burner 51 and its supports 53 may be passed when it is desired to remove the gas burner. Gas is supplied to the gas burner 51 through a detachable coupling 56, having suitable connection with a supply pipe 57. Rigidly connected with the lower surface of the bottom wall of the casing 1 are horizontal tracks 58, which are disposed upon opposite sides of the opening 55. These tracks support a removable perforated ash receptacle 59, provided upon its upper longitudinal edges with flanges 60, which slidably engage the tracks 58. Removably mounted within the ash receptacle 59 is a grate 61, for holding coal or the like. This grate 61 is curved in vertical cross-section and is provided at its longitudinal edges with flanges 62, which engage inwardly extending flanges formed upon the inner surface of the ash receptacle 59. The front end wall of the casing 1 is provided at its lower end with an inlet opening 63 through which air passes to the gas burner 51.

In the operation of our stove we may either use the gas burner 51 or burn coal or the like in the grate 61. When the gas burner 51 is in use the ash receptacle 59 and the grate 61 may be removed. When coal or the like is burned in the grate 61 the gas burner 51 is previously removed. To remove this gas burner, the ash receptacle 59 and the grate 61 are first removed. The coupling 56 is now disconnected from the gas burner by suitable means. The removable supports 53 are disconnected from the fixed supports by the removal of the screws 54. Subsequently to this the removable supports 53 may be passed through the opening 55. The legs 52 have no connection with these supports 53 and hence the supports may be removed independently of the burner 51. The burner may now be removed.

The products of combustion or heated gases circulate about the ovens 23 and 24 and between the same and the inner shell 18 and finally discharge into the sleeves or flues 9 and then pass through openings 8. By proper manipulation of the valves or dampers 37 the proper amount of air may be introduced into the ovens 23 and 24. By proper manipulation of the dampers 43 some of the products of combustion circulating exteriorly of the ovens 23 and 24 may be introduced into such ovens.

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, we claim 1. A stove of the character described, comprising a plurality of spaced shells arranged one within the other forming air spaces therebetween having their upper ends closed and their lower ends open, an oven disposed in the innermost shell, a sleeve passing through the shells without establishing communication between them and serving as an outlet for the innermost shell, and a burner disposed within the lower portion of said shells. p
